Step 3: 1764 + 882 = 2646
Step 4: 2646 + 882 = 3528
Step 5: 3528 + 882 = 4410
Step 6: 4410 + 882 = 5292
Step 7: 5292 + 882 = 6174
Step 8: 6174 + 882 = 7056
Step 9: 7056 + 882 = 7938
Step 10: 7938 + 882 = 8820
Step 11: 8820 + 882 = 9702
Step 12: 9702 + 882 = 10584
Step 13: 10584 + 882 = 11466
Step 14: 11466 + 882 = 12348
Step 15: 12348 + 882 = 13230
Step 16: 13230 + 882 = 14112
Step 17: 14112 + 882 = 14994
Step 18: 14994 + 882 = 15876
Step 19: 15876 + 882 = 16758
Step 20: 16758 + 882 = 17640
Step 21: 17640 + 882 = 18522
Step 22: 18522 + 882 = 19404
Step 23: 19404 + 882 = 20286
Step 24: 20286 + 882 = 21168
Step 25: 21168 + 882 = 22050
Step 26: 22050 + 882 = 22932
Step 27: 22932 + 882 = 23814
Step 28: 23814 + 882 = 24696
Step 29: 24696 + 882 = 25578
Step 30: 25578 + 882 = 26460
Step 31: 26460 + 882 = 27342
Step 32: 27342 + 882 = 28224
Step 33: 28224 + 882 = 29106
Step 34: 29106 + 882 = 29988
Step 35: 29988 + 882 = 30870
Step 36: 30870 + 882 = 31752
Step 37: 31752 + 882 = 32634
Step 38: 32634 + 882 = 33516
Step 39: 33516 + 882 = 34398

So, 882*39 = 34398
